This is why I am glad I have an EcoBee thermostat. I can adjust it for home and away operations to cut down natural gas usage from the heating furnace when I’m not home.
Yes, Ecobee is nice. Can adjust from away from home, and it notices if nobody is home (no movement among 6 motion detectors) and adjusts heat/cool range accordingly - then resumes when occupancy is detected again.
Also lets me adjust the temps from my phone, improving experience of undoing others’ setting temps to stupid extremes (”I’m slightly cold, so setting temp to EIGHTY-FIVE in JANUARY”) without having to actually approach the unit (”don’t you dare change it back to a reasonable 72!” “ok” [taps phone, sets to 72]).
